Hello,
I have problem with using variables in loops. The problem is how to define a global variable which can get a value in loop. It may seem silly, but running the following code, I found that Fluent deletes value of any variable just after the loop runs for the second time.

(define x)
;;loop
(do (( cntr 0 (+ cntr 1) )) ((> cntr 10))
  (if (= cntr 0)
    (begin
      (define x 10))
    (begin
      (define x (+ x 1))
      (display x))
  )
)

How can I define variable 'x' ?

(define x) 
;;loop
 (do (( cntr 0 (+ cntr 1) )) ((> cntr 10))  
   (if (= cntr 0)    
      (set! x 10)   
     (begin
        (set! x (+ x 1))
        (display x)) ))
